PITCHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 573,818, dated December 22, 1896.

Application filed August 29,1896- Serial No. 604,261. (No n1odel.\y

L/o @ZZ whom it may concern:

Beit known that I, MAXIMILIAN GUETHLER, of the city of Baltimore and State of Maryland, have invented certain Improvements in Apparatus for Pitching Barrels, of which the following is a speciiication.

In the description of the said invention which follows reference is made to .the accompanying drawings, forming a part hereof, and in which- Figure l isa central vertical section of the improved apparatus. Fig. 2 is a similar section looking in the direction indicated by the arrow in Fig. l. Fig. 3 is a top view of the apparatus.

Referring now to the drawings, A is a pitchholding kettle supported within a cylindrical wheeled jacket B, which forms a fire-potor furnace. The furnace is provided with suitable grate-bars a, a fuel-door b, and a smokepipe c. The kettle A has a cover C in three parts, the central one of which is stationary and the others hinged to the central section.

D is a pipe secured within the central section of the cover to carry 0E smoke from the kettle.

E is a reservoir or tank, cylindrical in shape, situate within and near the bottom of the kettle A. It is suspended by bars cl from the central section of the cover C.

F is an inwardly-opening clack-valve attached to one of the heads of the reservoir E near its top to allow of the flow of melted pitch to the reservoir. Its inlet-opening is covered by a perforated disk e to prevent chips or other foreign matter in the pitch passing with the pitch to the reservoir. From the shell f of the clackvalve extends a pipe G, leading to any source of supply of air under pressure. It has a cock g to control the admission of air to the reservoir and a branch pipe II with a cock 7L, leading downward at the outside of the furnace, for a purpose hereinafter described.

I is a hollow barrel-holder, preferably of rectangular shape as seen from the top, secured in the central section of the cover C.

J is a pipe leading from near the bottom of the other head of the reservoir E, through the barrel-holder I, where it is suitably supportpast the clack-valve into the reservoir.

ed, to a point considerably above the barrelholder. Its head is perforated or slotted.

K is another barrel-holder consisting of fou r arms 7l, extending from a hollow central hub 7c, which is supported by a hollow stand m, having legs n.

The branch pipe II before alluded to .is screwed into the side of the hollow stand m. (See Fig. 3.)

L is a pipe whichv projects from the center of the hollow stand m and passes loosely through the barrel-holder K, having a perforated head.

rIhe operation of pitching barrels by means of this apparatus is as follows: Supposing the kettle to be filled with pitch, fire started in the furnace, and the cocks g and h closed, the pitch as soon as it becomes iiuid iiows An unpitched barrel is now placed on the barrelholder I, the pipe J entering the bung-hole of the barrel, which is considerably larger than the said pipe. The cock g is now opened, when air under pressure closes the clackvalve, and, passing under the valve, forces the hot melted pit-ch into the barrel. Owing to the head of the pipe J being perforated, the fluid pitch is distributed over the entire inner surface of the barrel and the surplus pitch, or that which does not adhere to the wood, runs back around the pipe J into the kettle. The cock g is now closed, and after the barrel is fully drained of the superfluous pitch it is removed from the holder I and placed over the pipe L, so as to rest on the holder K. The cock 7L is then opened and air forced into the barrel, which has the effect of chilling the coating of pitch, after which the barrel is removed in a thoroughlypitched condition.

As soon as the cock g is closed the reservoir begins to fill,and the operation of pitching barrels may therefore be a nearly continuous one.

It will be seen that there is no exposure of the pitch or opportunity for the same to chill during the pitching operation, the reservoir being kept in a hot condition by the surrounding pitch.

I claim as my invention;-

IOO

1. In an apparatus for pitching` barrels, the combination of a kettle and means to heat it, a reservoir submerged in the melted pitch in the kettle, an inwardly-opening Valve to admit melted pitch from the kettle to the reservoir, and an air-blast to drive the melted pitch from the reservoir to the interior of a barrel, substantially as specified.

2. In an apparatus for pitching barrels, the combination of avpitch-kettle and means to heat it, a pitch-reservoir submerged in the melted pitch, an inwardly-opening Valve t0 allow of the flow of melted pitch from the kettle to the reservoir, a compressed-air pipe leading into the shell 0f the said Valve, and a second pipe leading to a barrel, whereby the charge of melted pitch in therreservor 1 is injected into the barrel, substantially as specified. In an apparatus for pitching barrels, the combination of a furnace, a pitch-kettle in the furnace, a reservoir within the kettle, an K inwardly-opening valve leading to the reservoir to admit of the filling of the same with r GUETHLER.
